Latest Patents

Linus holds a patent for a "Method for preprocessing speech for digital audio quality improvement." This invention focuses on preprocessing speech signals from an indirect conduction microphone. The method is executed in two stages. In the first stage, an external speech sample is characterized using an auto regression model. Coefficients from this model are convolved with the internal speech signal from the indirect conduction microphone to produce a pre-conditioned internal speech signal. In the second stage, a training sound is received by the indirect conduction microphone and filtered through a low-pass filter. The result is then modeled using auto regression and inverted to create an inverted filter model. The pre-conditioned internal speech signal is convolved with this inverted filter model to eliminate negative or undesirable acoustic characteristics and loss from the speech signal.
